Aaron Klotz	da078b4c09	util/winutil: add package for logging into Windows via Service-for-User (S4U) This PR ties together pseudoconsoles, user profiles, s4u logons, and process creation into what is (hopefully) a simple API for various Tailscale services to obtain Windows access tokens without requiring knowledge of any Windows passwords. It works both for domain-joined machines (Kerberos) and non-domain-joined machines. The former case is fairly straightforward as it is fully documented. OTOH, the latter case is not documented, though it is fully defined in the C headers in the Windows SDK. The documentation blanks were filled in by reading the source code of Microsoft's Win32 port of OpenSSH. We need to do a bit of acrobatics to make conpty work correctly while creating a child process with an s4u token; see the doc comments above startProcessInternal for details.

util/winutil: add package for logging into Windows via Service-for-User (S4U)

This PR ties together pseudoconsoles, user profiles, s4u logons, and
process creation into what is (hopefully) a simple API for various
Tailscale services to obtain Windows access tokens without requiring
knowledge of any Windows passwords. It works both for domain-joined
machines (Kerberos) and non-domain-joined machines. The former case
is fairly straightforward as it is fully documented. OTOH, the latter
case is not documented, though it is fully defined in the C headers in
the Windows SDK. The documentation blanks were filled in by reading
the source code of Microsoft's Win32 port of OpenSSH.

We need to do a bit of acrobatics to make conpty work correctly while
creating a child process with an s4u token; see the doc comments above
startProcessInternal for details.
